Thank you for your question. What you’re noticing is very common, especially when smiling—the muscles around the eyes can create fine lines or an extra crease as they contract. Botox can help, but only in certain situations. If the crease is caused mainly by muscle movement when you smile, a small amount of Botox placed carefully around the outer eye can soften that contraction and reduce how much the crease forms. However, if the crease is due to skin laxity, volume loss, or a natural fold, Botox alone may not fully correct it. In those cases, other treatments may work better, such as: Under-eye skin boosters (like HA micro-fillers) to smooth and hydrate the area Light under-eye filler to support the tissue if there's slight hollowing Laser or RF treatments to improve skin texture and elasticity Most of the time, a combination approach gives the most natural result. The good news is that this type of crease is very treatable, and even subtle adjustments can make a noticeable difference when you smile.
